Number of people = 5 (Suzanne, Barry, and 3 friends)
Number of bagels = 4
4 bagels divided between 5 people is 4/5.
U subtract 4x by 5x and then you add 3 by -21 and the answer is x=18
377m total people can drink
780 (or c)
I think this is correct because 4 x 5 = 20 x 5 = 100 and 100 x 5 = 500
500 + 280 = ????
780
12/20 is equivalent to 3/5. <span />
